Answer this question truthfully
### Question: What causes Byssinosis?
### Response: Breathing in the dust produced by raw cotton can cause byssinosis. It is most common in people who work in the textile industry. Those who are sensitive to the dust can have an asthma -like condition after being exposed. In those with asthma, being exposed to the dust makes breathing more difficult, but in byssinosis, the symptoms usually go away by the end of the work week. After long periods of exposure, symptoms can continue throughout the week without improving.
Methods of prevention in the U.S. have reduced the number of cases, but byssinosis is still common in developing countries.
